Study summary

Colchicine is the drug of choice to treat patients with Familial Mediterranean Fever (FMF ), some of the patients treated with colchicine may suffer from gastrointestinal (GIT) adverse effect such as diarrhea and abdominal pain especially in the higher dose.

5-10% of the patients with FMF that have been treated with colchicine may have partial or no response to this therapy.

Aim of our study: the aim of our study is :.1to evaluate the efficacy of probiotics in reducing the number of adverse effect in patients with FMF that are being treated with colchicine and suffering from GIT adverse effect.

.2 To evaluate the efficacy of probiotics in reducing the number of FMF attacks in children with FMF that has been treated with colchicine with only partial response.

Methods: the study will be done among children (5-17 years old) with FMF that are currently followed in the pediatric rheumatology clinic at Mayer children hospital Israel Haifa that are being treated with colchicine and suffering from either GIT adverse effect or partial response to colchicine.

The study is design to be double blind placebo control, in the first 3 month patients will be with no therapy and will be required to record all there FMF episodes and their GIT adverse effect, in the second period the patients will be randomly divided into two groups 1.patients that will received placebo (group 1) and the 2. Probiotics group - patients will received probiotics (Bio -25 including 11 types of bacteria L.acidophilus, B.bifidum , L.rhamnosus, L.lactis, L.casei, B.breve, B.thermophilus, B.longum, L.paracseis, L.plantarum, B.infantis), both for three month, during this period patient will be required to record their gastrointestinal symptoms and other symptoms that may be related to FMF.

What researchers measure

Primary outcomes

  1. The number of gastrointestinal adverse effect related to colchicine therapy after adding probiotics to colchicine therapy.

    The number of gastrointestinal adverse effect will be measured 3 months before starting the intervention and after 3 months patients will received either placebo or probiotics the measures will be : 1. Number of days with at least one episode of loose stool. 2. Number of days with abdominal pain not related to FMF attacks.

    Time frame: 6 months after enrollment assumed to be at 12/2014

Secondary outcomes

  1. Number of FMF attacks after adding the probiotics to the colchicine therapy

    The number of attacks will be measured 3 months before starting the intervention and after 3 months patients will received either placebo or probiotics . Attacks will defined as fever with one of the above : a. abdominal pain b.pleuritic chest pain c.arthritis d.erysipelas like .

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 7, 2016, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
